Debunking the Left's Attack
on an Innocent Climate Scientist

“The whole point of science is to question accepted dogmas.
For that reason, I respect Willie Soon as a good scientist and a courageous citizen.’’

— Freeman Dyson, Boston Globe, November 5, 2013

“The Heartland Institute stands four-square behind Willie Soon. He’s a brilliant and courageous scientist devoted entirely to pursuing scientific knowledge. His critics are all ethically challenged and mental midgets by comparison. We plan to continue to work with Willie on future editions of Climate Change Reconsidered and feature him at future International Conferences on Climate Change, including the next one, the tenth, scheduled to take place in June in Washington, DC.

— Joseph L. Bast, president, The Heartland Institute

“The truth is that the Smithsonian received a number of grants and then paid Dr. Soon and others salaries and travel expenses. Dr. Soon’s immediate source of funding was the Smithsonian. Nothing more needs saying about this entire issue.”

— Dr. Christopher Essex, University of Western Ontario

[This page was last updated on April 21, 2015.]

In late February, 2015, Dr. Wei-Hock “Willie” Soon was accused by a Greenpeace activist of failing to disclose conflicts of interest to an academic journal. The accusation was false, but it was repeated by liberal reporters for major media outlets in the U.S. and U.K. and then became the basis for a coordinated campaign against global warming “skeptics” by liberal advocacy groups, Democratic U.S. senators and a congressman, and their allies in the mainstream media.

This page presents background information and facts about the controversy as well as links to some of the attacks on Dr. Soon as well as articles defending him. Dr. Soon's biography and a partial list of articles he has written for peer-reviewed journals is at the bottom of this page.

* Neither the editors of Science Bulletin nor the Smithsonian Institution, Dr. Soon’s employer, have said Dr. Soon violated their disclosure or conflict of interest rules.

* Kert Davies, the source of the accusations, has been making similar attacks against Dr. Soon and other climate scientists since as long ago as 1997. He is not a credible source.

* Grants supporting Dr. Soon’s work were vetted and submitted by the Smithsonian, not by Dr. Soon. Grant dollars went to the Smithsonian, which kept around 40 percent of the money for oversight and overhead.

* The amount of industry support Dr. Soon received, variously reported as $1 million or $1.2 million, includes the Smithsonian Institution’s 40 percent share and was received over the course of ten years.

* By agreement between donors and the Smithsonian, Dr. Soon wasn’t even aware of who some of the donors were, making a conflict of interest impossible.

* Disclosure of funding sources is not a common requirement of academic journals in the physical sciences field. Most climate scientists – alarmist as well as skeptical – do not disclose their funding sources.

* The Smithsonian’s investigation into its grant-making process is being led by John Kress, Interim Under Secretary for Science,, and Charles Alcock, director of the Center for Astrophysics,


* Before this phony controversy erupted, Why Models Run Hot” was downloaded from Science Bulletin some 10,000 times in just a few weeks — a very high number for a scientific paper. As of February 26, the paper has been downloaded more than 22,000 times (combined paper downloads and abstract readings), more than any other paper in the publication’s history.

* The Harvard-Smithsonian Center for Astrophysics expressly forbids Soon to research and write about climate change while “on the clock” because it is allegedly unrelated to the center's focus. So it necessarily follows that the grants Soon raises to fund his position at Harvard-Smithsonian — which are agreements between the Harvard-Smithsonian Institution and donors, not between donors and Dr. Soon — did not pay for “Why Models Run Hot."

* Soon stated to the Boston Globe in 2013: “No amount of money can influence what I have to say and write, especially on my scientific quest to understand how climate works, all by itself.”

* The leftist Guardian newspaper reported on February 21, 2015 that Soon's arrangement with Harvard-Smithsonian is one in which he raises his own salary. This is not unusual and doesn’t mean he’s in a junior or inferior position at the center: “As is common among Harvard-Smithsonian scientists, Soon is not on a salary. He receives his compensation from outside grant money, said Christine Pulliam, a spokeswoman for the Center for Astrophysics.”

Harvard-Smithsonian is publicly defending Soon: “Pulliam cast Soon’s association with the institutions as an issue of academic freedom: 'Academic freedom is critically important. The Smithsonian stands by the process by which the research results of all of its scholars are peer reviewed and vetted by other scientists. This is the way that the scientific process works. The funding entities, regardless of their affiliation, have no influence on the research.' ”

* Fifty-seven scientists sent a letter to the Harvard-Smithsonian on June 7, 2010 urging the center to reject the Greenpeace FOIA request in order to “protect Dr. Soon, to safeguard the integrity of the research process, and to reject this effort to bring undue and improper political influence to bear on scientific activities.” Read the letter here.

* Climate scientists who favor the alarmist perspective seldom disclose the funding they receive from left-wing advocacy groups or government agencies whose RFPs clearly call for alarmist findings. For example, Michael Oppenheimer (See Why Doesn’t Boston Globe do funding story on UN IPCC & EDF Warmist Michael Oppenheimer?) and (Oppenheimer, a paid partisan of the environmental pressure group Environmental Defense) and Kerry Emanuel: (National Academy of Sciences to investigate warmist Kerry Emanuel for failing to disclose insurance industry ties in recent study and Winning! JunkScience forces Emanuel to disclose insurance employers.) 

None of the attack pieces dispute the science Soon presents. This is because the journalists simply took a news release from Greenpeace, a radical environmental group with no expertise on climate science and a record of exaggeration and attacks on climate scientists, and reported it as news. The "science reporters" assigned to these hit pieces — even from America's most prestigious outlets —don't know enough about science to comment on the merits of Dr. Soon’s work. 

That the Harvard-Smithsonian Center for Astrophysics accepts outside funding to support the work of Dr. Soon and other scientists on its staff is old news. Kert Davies, the source of the latest smear, has been trying to demonize Dr. Soon and the Smithsonian Institution about this since 1997This latest attempt to smear Dr. Soon and the Harvard-Smithsonian Institution is timed to distract attention some real news that exposes real corruption in the global warming movement:  the resignations of the nation's "greenest" governor, John Kitzhaber of Oregon, and the chairman of the United Nations' Intergovernmental Panel on Climate Change (IPCC) Rajendra Pachauri.

Dr. Soon’s complete dossier and curriculum vita is here.

Dr. Wei-Hock "Willie" Soon, an astrophysicist and geoscientist, is a leading authority on the relationship between solar phenomena and global climate. His discoveries challenge computer modelers and advocates who consistently underestimate solar influences on cloud formation, ocean currents, and wind that cause climate to change. He has faced and risen above unethical and often libelous attacks on his research and his character, becoming one of the world’s most respected and influential voices for climate realism.

Dr. Soon earned his bachelor’s and master’s degrees in science and his Ph.D. in aerospace engineering from the University of Southern California.

Since 1992, Dr. Soon has been an astronomer at the Mount Wilson Observatory. He is also receiving editor in the area of solar and stellar physics for New Astronomy. He writes and lectures both professionally and publicly on important issues related to the sun, other stars, and the Earth, as well as general science topics in astronomy and physics.

Dr. Soon’s honors include a 1989 IEEE Nuclear and Plasma Sciences Society Graduate Scholastic Award and a Rockwell Dennis Hunt Scholastic Award from the University of Southern California for Athe most representative Ph.D. research thesis” of 1991. In 2003, he was invited to testify to the U.S. Senate.

Also in 2003, Dr. Soon was recognized, with a monetary award, for Adetailed scholarship on biogeological and climatic change over the past 1,000 years” by the Smithsonian Institution. In 2004, Soon received the Petr Beckmann award of the Doctors for Disaster Preparedness for “courage and achievement in defense of scientific truth and freedom.” In 2014, Dr. Soon received the “Courage in Defense of Science Award,” with a monetary award, from the George C. Marshall Institute. The award was presented at the Ninth International Conference on Climate Change held in Las Vegas.

Dr. Soon is the author of The Maunder Minimum and the Variable Sun-Earth Connection (World Scientific Publishing Company, 2004). He is the coauthor, with Sebastian Lüning, of Chapter 2: “Solar Forcing of Climate,” in Climate Change Reconsidered II: Physical Science (The Heartland Institute, 2013), a comprehensive critique of the Working Group I contribution to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. His research has appeared many times in peer-reviewed journals, including the following:
